In some versions of Helicon Remote, a dialog box will pop up asking for the D2XXhelper driver to be installed.But this information is misleading for the WeMacro control box. If this driver is installed it will cause the Helicon Remote and WeMacro macOS programs to fail to recognise the control box.
Here’s how to uninstall D2XXhelper
First,please use go to folder function
Then enter /library
Find the extensions folder in library
Go to the extensions directory, find the D2XXhelper file and drag this file to the trash.
At this point, the HeliconRemote or WeMacro program should be able to recognize the control box when opened again.
If it is still not recognized, try installing this driver file，link
